XRT73LC00A
55
E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.0.2
This Read/Write bit-field is used to configure the Receiver in the XRT73LC00A to output the recovered data on
either the rising edge or the falling edge of the RCLK2 clock signal.
Writing a “0” to this bit-field configures the Receiver to output the recovered data on the rising edge of the
RCLK2 output signal. Writing a “1” to this bit-field configures the Receiver to output the recovered data on the
falling edge of the RCLK2 output signal.
Bit D0 - RCLK1INV (Invert RCLK1)
This Read/Write bit-field is used to configure the Receiver in the XRT73LC00A to output the recovered data on
either the rising edge or the falling edge of the RCLK1 clock signal.
Writing a “0” to this bit-field configures the Receiver to output the recovered data on the rising edge of the
RCLK1 output signal. Writing a “1” to this bit-field configures the Receiver to output the recovered data on the
falling edge of the RCLK1 output signal.
5.1.5
Command Register - CR4
Bit D4 - Reserved
This bit-field has no defined functionality
Bit D3 - STS-1/DS3 Mode Select
This Read/Write bit-field is used to configure the XRT73LC00A to operate in either the SONET STS-1 Mode or
the DS3 Mode.
Writing a “0” into this bit-field configures the XRT73LC00A to operate in the DS3 Mode. Writing a “1” into this
bit-field configures the XRT73LC00A to operate in the SONET STS-1 Mode.
NOTE: This bit-field is ignored if the E3 bit-field (D2 in this Command Register) is set to “1”.
Bit D2 - E3 Mode Select
This Read/Write bit-field is used to configure the XRT73LC00A to operate in the E3 Mode.
Writing a “0” into this bit-field configures the XRT73LC00A to operate in either the DS3 or SONET STS-1 Mode
specified by the setting of the DS3 bit-field in this Command Register. Writing a “1” into this bit-field configures
the XRT73LC00A to operate in the E3 Mode.
Bit D1 - LLB (Local Loop-Back)
This Read/Write bit-field along with RLB (bit D0 in this Command Register) is used to select which Loop-Back
mode the XRT73LC00A operates in. Table 6 relates the state of the LLB and RLB to the selected Loop-Back
mode.
Bit D0 - RLB (Remote Loop-Back)
This Read/Write bit-field along with LLB (bit D1 in this Command Register) is used to select which Loop-Back
mode the XRT73LC00A operate in. Table 6 relates the state of the LLB and RLB bits to the selected Loop-
Back mode.
5.2
Operating the Microprocessor Serial Interface.
The XRT73LC00A Serial Interface is a simple four wire interface that is compatible with many of the
microcontrollers available in the market. This interface consists of the following signals:
